BALING-PBESS.

, To all whom it may concern:

I whereby a direct operating pull connection can be had between the power and plunger,

and the bale delivered toward the power; to

provide a cushioning means to neutralize the shock caused by the rebound of the plunger; to provide a simple and eflicient feeder to automatically force the material down into the press-chamber; and to provide means for tucking in the loose ends of the material which projects when the plunger 'is retracted; and consists, preferably, in the construction hereinafter described, which may be varied without departing from the spirit of my invention.

Figure 1 is a side elevation of a baling press, parts being broken away to better show the interior construction; Fig. 2 is a plan view of the same, also parts broken away; Fig. 3 is a longitudinal sectional view of plunger, air cushion and a part of bale-chamber; Fig. 4 is a plan view of the plunger; Fig. 5, a side view of the tucker; Fig. 6, a View of a part of tucker with parts broken away showing tension mechanism; Fig. 7 a side elevation of the upper sheave of the feeder mechanism; Fig. 8, a plan view of Fig. 7 and Fig. 9, a sectional end view of the baling-case and chamber.

Referring to the drawings, similar numerals of referenceindicate corresponding parts in the difi'erent views, and, referring to the same, the baling-case is formed with the usual sides 1, top 1 and feed opening 2. An angle bar 3 (Fig. 9) is fixed to and extends along the outer lower portion of each side 1. The bottom of the baling-case is formed of a stationary portion or member 4 and a movable portion or member 13. Member 4 is secured to angle bars 3 and extends longitudinally from a suitable point within the baling-chamber 4 to any suitable distance toward the front or power end of the machine. Beneath bottom 4 are two Z bars Specification of Letters Patent.

italftrtalt 5, the upper flange of each of which turns outwardly and the lower flange turns inwardly. The outwardly extending flange of each Z bar is secured to bottom 4: and to angle bar 3, and the inner face of each web of Z bars 5 and the inner face of sides 1 are in vertical alinement.

Plunger 6, comprises the front plate 7 and top plate 7 which are secured to supports 8, the supports being mounted on two beams 9, preferably I beams, which are suitably se cured together. Beams 9 are provided near their ends with rollers 10 and 11 which are adapted to run on the inwardly projecting flanges 5 of Z bars 5. The forward ends of beams 9 are also provided with laterally mounted anti-friction rollers 12, which roll against the inner face of Z bars 5. A plate 13 is secured to the top of beams 9 and its width is practically equal to the distance between Z bars 5, but with sufficient clearance to permit a free reciprocating movement between the same. Z bars 5, beams 9 and rollers 10 and 11 are so proportioned as to permit beams 9 and plates 13 to pass beneath stationary bottom 4 of the balingchamber as they move forward and back on flange 5 of Z bars 5.

It is apparent that the distance which bottom 4 shall extend rearwardly is governed by the extreme forward movement of the plunger. Plate 13 must be of sufiicient length toextend from plate 7 when plunger is in retracted position, to a point a short distance underneath the rear end of bottom 4: in order to furnish a bottom for the baling-chamber between the plunger and end of bottom 4. Plate 13 thus forms the mov able portion or member of the bottom of the baling-case.

In drawings (Figs. 1 and 3) is shown a lateral recess 8 in supports 8, beneath the lower edge of plate 7, of such dimensions as to permit the entrance of bottom a when the plunger is drawn forward to the maximum distance. It is not essential, however, to construct the plunger with this recess 8 as plate 7 may extend downwardly to plate 13. In such case, bottom 4 will be shortened at its rear end a suflicient amount to permit the plunger to advance its full stroke or maximum distance. Plate 13 would also be lengthened to close the gap between plate 7 and bottom 4, thus occasioned, when the plunger is in its retracted position.

At the forward end of beams 9 is a cross piece 9 to which is attached pull bar 9*, the forward end of bar 9 is adapted to be connected with the power mechanism. The power by which the press may be operated is not shown in the drawings as it may be connect-ed with and driven by any motive power.

Attached to the plunger, as on the rear sideof plate 7, is fixed a cylinder 14 having therein a spring 15 and a piston 16. The piston rod 17, which is attached to piston 16, extends rearwardly from the cylinder and is adapted to strike plate or strap 18, which is secured to the baling-case or frame. Suitable openings 19 in cylinder l-ft at the rear of piston provide communication between the interior of that cylinder and the outside. It is apparent that as the plunger rebounds, upon the release of the power pressure thereon, it travels very rapidly rearward. When piston rod 17 strikes end plate or strap 18, piston 16 is thereby driven forward and. compresses the air in front of it which takes up or cushions the momentum of the plunger and thereby relieves the shock and a1 to the mechanism which would occur except for this cushion. Spring 15 is also compressed by this forward movement of the piston 16 and when plunger 6 moves forward again thisspring forces the piston outwardly into its normal position for the next rebound of the plunger. It is apparent that the position of the cylinder 14 could be reversed; that is, fixed to the end plate or strap 18, or other suitable stationary part, with the piston rod 17 extending forwardly therefrom and arranged so it would be struck by the plunger 6 as it rebounds rearwardly with the same result. The operation of the device is identical in either position. On each side of the baling-case and adjacent to the feed opening 2, is fixed a bracket 20. These brackets support a shaft 21 which carries feeder 22. This feeder comprises arms 23 which are attached to and extend from shaft 21 and connected at their outer end by plate 22.

Any form of feeder will suflice for my purpose, such apparatus being old in the art. Feeder 22 is adapted to be raised and lowered through feed-opening 2 for the purpose of forcing the material being baled down into the baling-ehamber. Motion is imparted to feeder 22 in the following manner: Shaft 21 carries a double sheave 24, preferably, on each of its ends, which ends project beyond the sides of the baling case. These double sheaves each comprise an outer portion 24 and an inner portion 2 1 These two portions are provided with matching serrations 24 and the two portions are secured together in an adjusted position of the two serrations relative to each other by bolt 2 1, which bolt passes through suitable openings in the two portions, one of the openings being a slot to provide adjustment of the two portions. This adjustment of the two portions of sheave 24 is provided in order to regulate the limit of the downward movement of the feeder. A similar double sheave 25 is provided on the exterior of the lower portion of each side of the baling-case and in vertical alinement with the sheave above it. A chain 26 or other suitable means is attached at one of its ends to the outer portion of sheave 24, as by pin 24, and passes forwardly over that member, the lower end thereof being attached to the rear face of the outer portion of sheave 25, as by pin 25 Another chain 26, having a spring or other tension portion 27 therein, is attached at its lower end to the forward face of the inner portion of sheave 25, as by pin 25, and is carried upwardly and over the rear face of sheave 2%, the upper end being connected to the rear end of tension spring 28, the other end of said spring 28 is attached to the baling-case, as by hook 28 and bolt 28 having adjustment in slot 28 or other suitable manner. Both the chain 26 and spring 28 are also attached to the inner portion of sheave 24c in a suitable manner as by pin 29. A similar system of connections is provided between the double sheaves on the opposite side of the balingcase. Lower sheaves 25 are provided with a number of teeth thus forming segment gears which may be bevel or spur gears and which are adapt-ed to meshwith racks 30, or other suitable means adapted to rock said gears, said racks being preferably secured to beams 9 of plunger 6. As plunger 6 moves forwardly racks 30 mesh with segment gears of sheaves 25, and rock these gears and sheaves toward the rear of the machine producing a pull on the chains 26 which causes sheaves 24: to rock in the opposite direction. This rocking of sheaves 24 also rocks shaft 21 forwardly which thereby elevates feeder 22 to the position shown in dotted lines in Fig. 1. On the rebound or retraction of plunger 6 to its normal posit-ion the segment gears and sheaves 25 will be rocked forwardly by racks 30, which rocking, through the connecting chains 26 produces a rearward motion to sheaves 24 and shaft 21, by which feeder 22 is lowered into the baling chamber. Springs 28 and 28 are thereby extended and the tension thus produced on said springs tends to pull the feeder up and hold it in normal position until the rebound or retraction of the plunger brings it down again. These springs could be of sufiicient strength to raise the feeder without the use of the elevating feature of the double sheave, but it is preferred to make the elevation of the feeder positive by the use of the double sheaves and chain arrangement. On the inside of lower sheave 25 is a lug 31 which is adapted to come in contact with a stationary mating lug 32 on the side of the baling-case, by which contact the upward movement of the feeder 22 is limited, the springs 28 and 28 holding the feeder in the raised position as fixed by the contact of said lugs. These lugs are so positioned on their respective surfaces that, when they are in contact, the segment gears of sheaves 25 will be in position to mesh with racks 30, as the plunger moves rearwardly. Springs 27 in chains 26 are intended as a safety device to relieve the parts from any shock or excessive strain that may occur in case the feeder 22 should meet with any abnormal resistance as it descends into the baling chamber.

lVhile members Ql and 25 are described as sheaves, it is understood, of course, that any suitable form of pivoted member will suflice, the purpose being to produce an efiicient mechanism for operating a feeder of what is termed a pull power press, that is, where the plunger moves toward the power end of the machine while pressing the charge, my intention being to transform the motion of the reciprocating parts of the device into a rocking movement for the feeder.

Extending laterally from each bracket 20 is a pivot 31 on which is pivotally mounted a tucker 32*, which comprises a yoke or bracket 33 having two depending members or arms 34 each provided with an opening in the lower extremity by which the yoke or bracket is adapted to be pivotally supported on pivots 31. Yoke or bracket 33 is of sufficient height to clear the top of the balingcase 1 and the upper portion 34E of it is projected rearwardly toward feed opening 2. This upper portion carries a plate 35 the rear part of which is bent downward and forwardly to form the tucker blade 35 which extends transversely across the forward end of the feed opening 2. In normal position blade 35 extends downwardly and forwardly a short distance into the balingchamber 4c The pivots 31 are arranged at a point forward of and below the plane of the lower edge of blade 35 so that as the plunger advances forcing the material forward the action of the latter against the sloping blade 35 forces or rolls it forwardly and upwardly in a circle about its pivots while the material passes under it, then when the plunger has retracted rearwardly the tucker is restored to its normal position by means illustrated in Figs. 5 and 6. It consists of a torsion spring 36 which encircles pivot 3l one end of which is engaged in an opening in arm 34 of the tucker. The other end of the spring is engaged in an opening provided in housing 37 which incloses the spring 36 and extends outwardly along pivot 31 The outer end of housing 37 is reduced and provided with a number of openings or notches 38. Pivot 31 is pro vided with a hole 39 in such position that pin 39 may be inserted into it, which pin will also engage one of the notches 38. The notches might be arranged so that pin 39 could engage diametrically opposite notches. Housing 37 may be provided with plane surfaces 40 to which a wrench may be applied to turn the housing about the pivot, thereby increasing or decreasing the tension of spring 36 as desired. When the desired tension is given spring 36 pin 39 is then inserted in hole 39 and engaged in notches 38, by which the housing is held to the pivot in adjusted position.

It will be noticed that the tendencies of torsion springs 36 is to force tucker 32 to its normal and lowest position within the baling chamber; the tension on those springs must, therefore, be sufficient not only to force down the tucker but also to force down with it the loose ends of material which project from the compressed mass after the plunger has retracted to the rear, so that on the next compression those loose ends will be folded down and caught within the bale. Since the motion of tucker 32" is downward and rearward its effect is ideal in forcing down loose material, for a tucker having that motion gathers in the loose material and effectually works it down for later com pression and assures the production of a smooth bale.
